The Arch MK3 is 24% wider than the previous model but keeps the same low weight!
Redesigned for 2017 using their "wide but not crazy wide" WideRight theory. The Arch MK3's 26mm internal width has been designed with 2.25" - 2.5" rubber in mind, making it ideal for trail, and all mountain use.
Utilising Stan's Bead Socket Technology (BST), these rims are designed to make seating tubeless tyres a breeze with as little swearing and heavy breathing as possible. The fit is snug enough that you'll be able to seat most tyres with just a track pump but not so tight that you'll need metal tyre levers to get them on and off.
